-'tfi' patented January 24, 1888, and 392,71() patented November 13, 1888, to The Cincinnati rllype Foundry as assignee of Henry Barth and Ernst Lietze, and reference may be had to the said Letters Patent for specific information as to the general features of construction and arrangement of parts of the machine referred to in this specification and which are not specifically illustrated by the drawings which form a part of this speciication, and which are not specifically described in this specification.

rI'he objects of this invention are to iinproie type-casting machines of the general character illust-rated and described in the United States Letters Patent hereinbefore referred to, so that they can be run at a higher speed with an increased output of type as compared with the olderforms of machines for the same period of operation, and to improve the construction of. such 'type-casting machines in the manner to be hereinafter specifically described and claimed. I

.Referring to the drawings which accompany this specification and form a part thereof, which drawings illustrate embodinients of this invention and on which drawings the same reference characters are used to designate the same elements wherever they may appear in each of the several views, Figure 1 is a front elevation of part of a type-casting machine, a part being broken away to show clearly the construction of a part of the machine; Fig.V 2 is a front elevation of part of the machine, parts being broken away and parts being shown in section, the View being similar to the view shown by Fig. 1, but showing movable parts of the machinein different positions Afrom the positions which the said movable vside thereof,

parts occupyin Fig. 1; Fig. 3 is a rear ele- `ration of part of the machine; Fig. -t is a plan view on a somewhat larger scale of a part of the machine taken on the line o o, Fig. 1; Fig. 5 is a plan view of a part of the machine taken on the line ZL-Z), Figs. 2 and 8; Fig. G is a vertical section of a detail, taken on the line c-c on Fig. et; Fig. 7 is a horizontal section of a detail; Fig. 8 is a vertical section taken on the line cZ-d on Fig. S; Fig. 9 is an elevation, partly in sec` tion, taken on the line e-e on Fig. 8; and Fig. 10 is an elevation, partly in section, of a detail.

Referring specifically to the drawings, the reference numeral 1 designates the moldbeam of the .machine7 100 the mold, 2 the reciprocative mold-cover, which is reciprocated back and forth on the stationary mold- -beam 1 and over the top of the mold 100 by the connecting rod 3, which is moved by mechanism not shown by the vdrawings ac companying this specification, but which is well known. to those skilled in the art and which can be readily understood by reference to the United States Letters Patent hereinbefore referred to.`

The reciprocative mold-cover 2 is moved back and forth on the top surface of the mold-beam 1, which is level with the top face of the stationary parts of the mold, in

the ordinary manner, and the mold-cover 2 is retained in place laterally by the plates 4 and 5, which lare securely fastened to the moldebeam 1 by screws,l as shown by the drawings. rThe mold-cover 2 is provided with a guide member G projecting from each and extending rearwardly therefrom. These guide members 6 have their oppositekfaces parallel and these faces slide accurately between the plates t and 5. Secured on the tops of the plates et and and extending partly over the guide menibers G are holding-down plates 7 and 8.

rlhe mold-cover 2 is provided on its top with a yoke 9, in which is pivoted a lever 10 provided at one end with the anti-friction roller 11, which is adapted to ride under the cam bar 12 which is rigidlysupported in a fixed position by the standard 18, which in turn is adjustably secured to the rearvplate 5. Between the anti-friction roller l1 and the stud 14 is a pivot 15, on'k which is pivoted a rod 16, which is guided at its lower end in the mold-cover 2 so as to be retained in position while being free to move up and down, and surrounding said rod 16 a nd retained between the head 17 on said rod and mold-cover 2, is a spiral spring 18 of the open or compression type, which is constantly exerting its force to elevate the end of the lever 10 to which the anti-friction roller 11 is attached. The end of the lever 1() on the other side of the pivot 14 from the anti-friction roller 11 extends above a shoulder 19 formed on a plunger 20, which plunger will be hereinafter described more at length and which is capable of vertical movement.

The mold-cover 2 is provided with a pin 21 to serve as a stop, and an adjusting screw 22 provided with a lock nut 23, is received within a screwthreaded aperture in lever 10 in line with pin 21. The screw 22 can be so adjusted with respect to the lever 10 that when screw 22 contacts with pin 21, the downward movement of plunger 2O under the influence of spring 18 is accurately determined.

Fig. 1 of the drawings shows the movable A parts of the machine in the positions which channel to be hereinafter described, and the.

cam surface of cam bar 12 is so proportioned that when the parts are inthe posi- `tions shown the anti-friction roller 11 does not touch the cam har 12, as clearly shown by the drawings.

Fig. 2 of the drawings shows the movable parts of the machine in the positions which they occupy when a type has heen. cast and has just been freed from the mold and matrix, and in these positions of the parts it will he observed that the anti-friction roller 11 has rolled under the cam bar 12 and has been forced down so that the screw 22 no longer contacts with the pin 21 and the plunger 2O has been able to assume a more elevated position.

The machine is provided as usual with an upright 24 removably attached to the moldbeam by a bolt passed through a transverse bore or opening` formed as indicated in Figs. 1 and 9, and held in line by a feather. It is also provided with the usual plate 58 (commonly called nick guide) securely fastened to the mold-beam extending over and covering the right hand end of the mold and forming an end wall with its upper edge practically in line with the top of the mold (see Figs. 1, 2 and 5). Facing the nick guide 58 is an upright member 25, which is held in place laterally by guide fingers 26 and is supported from upright 24 by pins 27 and 28, which are immovably fastened to the upright member 25, but are slidable longitudinally in bore holes in upright 24, and

which are pushed toward the nick guide 58 by spiral springs 86, 87, and which can he drawn back and held back against the tension of the said springs by means of the thumb nuts 29 and 30, which are screwed onto the screw-threaded, reduced ends of said pins .27 and 28 respectively, in the ordinary manner.

The upright member and the nick guide 58 form a channel 31 in which the type are firmly held for grooving out Athe jet and trimming or rubbing by the knives 32 and 33, in the ordinary manner, and a part of this invention relates to this channel 31 as will hereinafter be more fully eX- plained and described. The type after passing between the knives 32 and 33 are pushed out from the tight channel 31 into a free or loose channel 34, from which they pass onto carrying sticks in the well known manner.

The case 35 is immovahly secured to the upright 24, as shown in Figs. 8 and 9, and the slidahle jaw bar 3G is reciprocativc within the same in the ordinary manner. and abuts against the mold-cover 2, as shown in Fig. 1 where the adjusting screw in the lug 7 8 forming a part of the slidable jaw bar is illustrated, except when the moldcover 2 is at its extreme limit of movement away from the channel 31, as clearly shown by Figs. 2 and 3 of the drawings. T he immovable upright 37 supports a rocker shaft 38, to which the crank arm 39 is securely fastened so as to rock the same, and the crank arm 39 is actuated by the connecting rod 40 which is pivoted thereto.

As shown in Figs. 1, 2, 4, 6 and 7, the clamp 41 is bifurcated or formed with two arms 44 and 45, which are adapted to seat upon a saddle member 4G, secured to the top of the mold-cover 2` in order to clamp the mold-cover tight upon the mold during the casting of a type when the molten type metal is forced in the usual manner into the mold by the pump (not shown). The clamp is also formed with a cylindrical stem 88 fitted in a corresponding bore in the boss 43 on one end of the rocker shaft 38 and having ay reduced threaded end 42 provided with a nut by which it is firmly fastened in said boss transversely to said shaft. Screws 4T and 48, threaded in the boss 43, with their heads overhanging and engaging seats on the clamp 41 above and below the center of the stem 88, afford A(means for turning the clamp about the axis of said stem when the nut thereon is loosened, and thus accurately adjusting the arms 44 and 45 vertically so that they will hear with equal pressure on opposite ends of the saddle member 46. A lifting member 49 is secured to the top of the boss 43 and is provided with a projecting toe 50, which when the parts are in the position to' discharge a type, which has been molded, into channel 31, extends under a projection 51 on plunger 20.

rlhe immovable upright 37 guides a vertically movable plunger rod 52, which car ries at its upper end an anti-friction roller 53. llhis plunger rod 52 with the anti-friction roller thereon is intended to force the plunger 2O downwardly to force a type, held between the inoldecover 2 and the slidable jaw bar 3G, down into the channel 31, in a manner to be hereinafterdescribed.

'lhe plunger 20 is movable vertically within a recess or cavity 5i within the moldcover 2, and a pusher plate 55 is secured to the plunger 20 and extends below the lower end thereof and is long enough and there is sufficient play between the lower end of the plunger 20 and the cavity or recess 5a so that when the plunger 20 is moved down wardly, the pusher plate can ,be moved below the lower surface of the mold-cover 2 and slightly into channel 31 when the movable parts of the machine are in the positions shown by Fig. 1 of the drawings. A spiral spring 56 norm ally pushes the plunger 20 upwardly and holds the pusher plate 55 elevated above the bottom of the mold-cover 2, and as is customary in this class of machines, the spring 56 is weaker than the spring 18. The spring 18 is the operating member which forces plunger 2O and pusher plate downwardly so that a type is securely held both between the jaws composed of the mold-cover 2 and the slidable jaw bar 36 and between pusher plate 55 and the top of the mold.

IType-casting machines of the character described in this specification and the United States Letters Patent referred to herein, have to be i'nade very carefully with the parts fitting as accurately as in high class scientilic instruments, and. while it is possible to make the machines practically perfect, the actual use of the machines will of coin-se destroy the original accuracy of construction. .ln other words, the machines will wear out and therev will come a time when parts will have to be discarded and renewed, or the parts resurfaced or relinished, but the adjustment provided for by the screws 47 and 48 in the boss 43 not only enables the arms 44. and L15 to be set originally to bear equally upon both ends of the saddle member 46, but these screws 47 and 4.8 provide for taking up looseness due to wear on one side or the other of the bottom of the mold-cover 2 or the top of the mold.

When running type-casting machines of the character described in this specification at a. high rate of speed, it has been found difficult to transfer or push a type from between the carrying jaws formed by the end of the mold cover 2 and the slidable aw bar 3G into the channel 31 by means ofthe pusher plate 55 and to withdraw the pusher plate 55 out of the channel 81, Without mishap.` In type-casting machines of thel same general character as that illustrated by the drawings accompanying this specification and more specifically illustrated and described in the United yStates Letters Patent hereinbefore referred to, a type which had been cast was carried forward from a point over the mold to the tight vertical channel designated on the drawings by the reference numeral by the reciprocating movements of themold-cover 2 and the slidable a-W bar 5G, and the overthrow movement of these members at the end of the stroke was generally limited by a positive stop. The pusher plate then pushed the type down into a tight channel, the channel being as tight as the springs behind the upright member 25 pressing against a column of type in the tight channel could make it. If the old style machines did not run too rapidly, a type would be delivered in the tight channel and the pusher plate 55 would retreat until stopped by plunger 2O coming in contact with lever 10, said lever 10 having been previously adjusted to the proper set in the manner well known to those lskilled in the art. A spring, like or similar to the spring 56, shown byl the drawings accompanying this specification, was relied upon iny the prior machines to lift the pusher plate 55 up out of the tight channel and to itseX-l treme upward limit of movement. If the type-casting machines of the prior art were run so fast that the spring 5G would not act quickly enough to lift the pusher plate 55 out of the tight channel, the pusher plate would be caught in the tight channel and bent or broken as the mold-cover 2 and the slidable jaw bar 86 moved to the left (see Fig. 1 of the drawings). This invention guards against any such accident because the pusher plate is positively lifted out of the channel and even with the top of the vmold by the lifting member 49, which is provided with the projecting toe 50 and which positively lifts the pusher plate 55, as hereinbefore described. Another source of trouble with the typescasting machines of this general character of the prior art, is experienced when a little too much oil has been placed on top of the mold to prevent cutting. rlhis oil gets onto the bottom of the pusher plate 55 and 'when a type was pressed down on top of the mold by pusher pate 55, a thin film of oil remained between the type and the pusher plate 55, and this oil remained there until the type was carried over to the tight channel and thepusher plate 55 had pushed the type down into the tight channel, but as the friction between the type and the tight channel was not always enough to detach the type from the bottom of the pusher plate 55 to which the type stuck on account ofthe aforesaid film of oil, the type would sometimes cling to the pusher plate and be lifted up with the pusher plate out of the tight channel and would be carried along to the left (see Fig. .l ofthe drawings) on top of the mold in which a new type had been cast, so that when the new type which had been cast was discharged from the mold, there would be two type, one on top of the other, and the machines were not Constructed to handle two type superimposed in this manner, and an accident would result, which generally required a stoppage of the machine for repairs.

This invention guards against a type sticking to the pusher plate 55 in the manner hereinbefore described, because the upward movement of the pusher plate 55 after it has pushed a type into the loose channel 57, is limited by the movable plunger rod 52 and the anti-friction roller 53, to the height of the top of the mold, and the several parts are so timed in their relative movements that the bottom of the pusher plate 55 is only raised to the height of the top of the mold until the mold cover 2 is moved far enough to the left (see Fig. 1 of the drawings) for the plunger 20 to be moved out from under the roller 53, so that if a type sticks to the bottom of the pusher plate 55 it will be wiped or scraped oif from the bottom of the pusher plate 55 as the pusher plate 55 moves to the left (see Fig. 1 of the drawings) away from the loose channel 57. The movement of the slidable jaw bar 30 to the left (see Figs. 1 and 2) is limited by the nut 90, being adjusted in such a manner that the said movement ceases just before the end of the slidable jaw bar 36 reaches the opening 'in the mold. This aifords an ample opening for the newly cast type to enter when pushed out of the mold by the body plate 101. Tt

also allows the type to be detached from the end of the body plate 101 by the movement of the mold cover to the right (see Figs. 1 and 2) before the type touches the jaw bar 3G in the well known manner. Moreover, in running the machine at a high speed the @is me@ of the reciprocating parts, viz: the mold-cover 2 and the parts carried thereby and the connecting rod 3, is such as to cause an overthrow of the moldcover 2 at both ends of its stroke. This overthrow is not objectionable when the mold-cover 2 is being moved toward the left hand, when looking at Figs. 1 and 2 of the drawings, but when the mold-cover 2 is being moved toward the right hand, serious ditliculty is encountered in transferring type from between the jaws formed by the end of the mold-cover 2 and the slidable jaw bar 3G into the channel 81. This invention overcomes this difficulty by beveling ofil the top edge of the upright member 25 as clearly shown by Figs. 1 and 2 of the drawings, thereby increasing the width of the channel 31 at the point where the type are delivered into the said channel 31, so that in effect the type are delivered one by one as they are cast into a loose channel 57 before they are forced into the tight channel 31. The type are cast with nicks and the nick guide 58, which as usual forms one side of the loose channel 57 and the tight channel 31, holds the type in proper register and alinement while they are being grooved on the bottom and shaved in passing through the tight channel 31. In order to move the type in the loose channel 57 against the nick guide 58, a pusher 59 is employed which may conveniently be constructed as a block seated in a slot 00, cut in the upper part of the upright member 25, and provided with a pin 61 which projects through the block on both sides thereof and is received within recesses 62 and 63 cut in the rear part of the upright member 25, as clearlyshown by the drawings. The block of the pusher 59 is provided with an extension 64 which is provided with a reduced portion 65, which are received within bores 66 and 67. A spring 68 is located in bore GG and bears against the end thereof, surrounds the reduced portion 05 of the eXtension 6e'. and bears against the shoulder on extension 64 to press the pusher outwardly. The pusher is also provided on its top with a projection 69 which is received within a slot 70 cut in the under face of the slidable jaw bar 36 and which slot is of such length that the slidable jaw bar 36 can move to its extreme position toward the left, Figs. 1 and 2, without the end of the slot contacting with projection G9, but when the slidable jaw bar 36 is moved to its eXtreme right hand position, Figs. 1 and 2, theend of the slot 70 contacts with the projection 69 and forces the pusher to the right against the tension of its spring 68, so that the whole width of the loose channel 57 formed by the beveling off of the upper part of upright member 25 is left clear for the type to fall or be pushed into. lVhen the slidable jaw bar 36 moves back again toward the left, the spring 68 shoves the pusher toward the left and j oggles the type over against the nick guide 5S with the nick of the type engaged therewith. The pin 61 limits the movement of the pusher 59 toward the left and it is preferred that the extent of movement allowed the pusher 59 is such as to push the type within a very small distance of the left hand side of the loose channel 57. the upright member 25, whereby the loose channel 57 is formed, is preferably of a depth sufficient to 'take in several type, as clearly shown by Figs. 1 and 2 of the drawings, and by the pusher 59 being limited The beveled upper end of in its movement so as not to be able to push the last type delivered to the loose channel 57 clear over to the left, the type in the loose channel will be sucessively tapped by the pusher 59 as each new type is deposited in the channel, and if a type should not be deposited in the channel with its nick in exact alinement with the nick guide 58, this successive tapping of the type in the channel as each new type is deposited therein, will cause that type to be moved lengthwise as the nick guide 58 engages with its nick, so that when the type reaches the top part of the tight channel 31 the type will be in proper alinement with the nick uide 58. The pusher plate 55 must move own between the ends of the mold-cover 2 and the slidable jaw bar 36 in the well known manner, but its upward stroke consists of two motions, iirst to top of mold and then to higher position, and at the same time a type which is being moved from the mold to the channels 57 and 31 must be held securely, but without being pinched, because the type in its movement is carried against a jet breaker 71 which is a knife which cuts the jet 72 off from the toot of the type 7 3, and between shaving or rubbing knives 71 and 75, which shave or rub the bur from two edges of the type, the burs on the other two edges of the type being shaved or rubbed ott by the knives 82 and 33 as the type pass through the tight channel 31, so the screw 76, provided with a lock nut 77', is screwed through a screw threaded aperture in the lug 78 on the top of the slidable jaw bar 36 to determine the kcloseness of approach of the end of the slidable aw bar 36 to the pusher plate 55. .lt will be understood of course, that the slidable jaw bar 36 is forced to the left, Figs. 1 and 2, by a spring 89 in the ordinary manner, and it is pushed to the right against the tension of such spring by the end of the mold-cover 2 bearing against the end or" screw 76.

ln the use of type-casting and iinishing machines of the character described in this speciiication, shavings of type metal and thin tins of type metal sometimes get between the movable and the stationary parts or' the machine, and the pusher 59 is preferably bili'urcated as clearly shown by Fig. 5 of the drawings, and lits loosely within the slot 60 so that there is plenty of clearance for any shavings or lins to escape, and the lower part of slot 60 is inclined away from the loose channel 57 so that any shavings or fins of type metal will drop clear of the type and will not be carried down with the type into the tight channel 31. When running type-casting machines of the character described in this specification at high speeds and more particularly when casting small bodied type, greatdifhculty has been experienced because the Jets 72 on the type when broken olii by the jet breaker 71, would ily all about the machine and create a general clutter. This ditliculty has been obviated by providing a cage 79 secured to the mold-cover 2 and inclosing the jet 72. is shown by the drawings, this cage is composed of a member 8O with an outstanding part 81 on top of which is secured a plate 82 with its end 83 bent down, as elearlyshown by Fig. 3 of the drawings, and a space 8i (see Fig. 5) is provided within which the jet breaker knife 71 can extend to cut oli the jet 72. The movement of the mold-cover 2 and the cage 79 to the left, as shown in Figs. 3 and 5 (to the right relative to Figs. 1 and 2) carries jet 72 over a pipe or chute 85 into which jet-chute or pipe the jet will drop and through which the jets can be conducted to any convenient point of discharge.

All unnecessary illustration of the details of the machine have been avoided, as they are well known and are illustrated and described in the United States Letters Patent hereinbefore referred to, and in describing the operation of the machine the parts not shown and their function will be only generally referred to for the purpose of making clear the improvements described in this specication and illustrated by the drawings accompanying the same.

The operation of the machine is as ollows: Referring first to Fig. 2 of the drawings, the parts are shown in the positions which they occupy immediately after a type 100 has been cast and a type has been raised by the body plate 101 from within the moldto the level of the top of the mold 100. This type is designated by the reference numeral 7 3. The mold-cover 2 is now moved to the 105 right bythe connecting rod 3, moving with it the slidable jaw bar 36 as soon as the end of the mold-cover 2 contacts with the end of the screw 76. lt is, of course, understood, as hereinbefore explained, that when the 1.10 slidable jaw bar 36 is moved to the left by spring 89 (following the movement of moldcover 2 to the left) its movement to the left is stopped by nut 90 contacting with the end of case 35 in the ordinary manner. During 115 this movement the anti-friction roller 11 rolls out from under the influence of the lower cam edge of cam bar 12 and the spring 18 being more powerful than the spring 56, swings lever 10 upon its pivot 14 120 and forces plunger 2O down, bringing the pusher plate 55 down into substantial contact with type 73, but the screw 22 having been adjusted properly, comes in contact with the pin 21 so that thetension of spring 125 18 cannot force the plunger 20 upon the type 73 with torce enough to destroy or injure the type. As the mold-cover 2 is moving toward the right, the saddle member 46 is being brought under the arms 44 130 and 45 of the clamp 41, and when the moldcover 2 is moved to its eXtreme limit of motion to the right, the connecting rod has been moved up, swinging up the crank arm 39 and depressing the arms and 45 of the clamp 41 onto saddle 46, and thereby clamping the mold-cover 2 tightly against the top of the mold, because it is when the parts are in this position that the pump (not shown) is forcing liquid type metal into the mold to cast a new type. Before the mold-cover 2v has reached its eXtreme limit of movement toward the right, the end oiI the slot 70, in the slidable jaw bar 36, contacts with the proj cction G9 on the pusher` 59 and further movement toward the right moves the pusher 59 to the right, so that the entire Tidth ot the loose channel 57 is eX- posed'for the reception of the type 73. the arms 44 and 45 of the clamp 41 were swung down toward and upon the saddle. member 46, the lifting member 49 swung down with the said arms so that its toe 50 was below the projection 51 on the plunger' 2O and the projection 51 on the plunger 2O was carried over the toe 50 of the lifting member 49 as the mold-cover 2 moved toward the right. This same movement carried the cage 79 (see Fig. 3 of the drawings, which is a rear elevation orP a part of the machine and the right and lett hand sides of the machine are consequently reversed) in the same direction, or to the right hand when loolrino' at Figs. 1 and 2. The plunger rod 52 with its anti-friction roller 53 is so timed as to move down and torce plunger 20 down when the type 73 and pusher plate 55 are above and opposite the loose channel 57, and the extent ol' this movement is such that the pusher plate 55 descends into said loose channel 57 so as to insure the removal of the type from the loose aw formed by the ends of the mold-cover 2 and the slidable jaw bar 3G into the loose channel 57. 1t will be understood that at this time in the operation of the machine a new type has been cast in the type mold and type 73 has been deposited in the loose channel 57 and the cycle of operation of the machine is completed by the parts returning from the position shown by Fig. 1 of the drawings to the position shown by Fig. 2 of the drawings. This return action is accomplished in the following manner: The arms 44 and 45 of the clamp 41 are released from saddle 4G by a downward movement of the connecting rod 40 and at the same time the toe 50 ot' the lifting member 49 is lifted up, (and provided spring 56 does not act) positively raising plunger 2O and withdrawing the pusher plate 55 completely out of the loose channel 57 with its lower end even with the top ot the mold. 1t should be stated now that the plunger rod 52 with its anti-friction roller 53 has commenced to rise either before or at the same time with the movement of the arms 44 and 45 of the clamp 41, and Fig. 1 of the drawings shows the plunger 2O as resting against the anti-friction roller 53. lhen the pusher plate 55 has been lifted entirely out of the loose channel 57 with its lower surface even with the top of the mold, the mold-cover 2 is pulled to the left by the connecting rod 3 and the spring 89 causes the slidable jaw bar 36 to follow the mold-cover 2 to the lett. This movement permits the pusher 59 to also move to the left to its eXtreme limit ot movement. As this movement of the moldcover 2 to the left continues, the anti-fric tion roller 11 rides under the cam bar 12, thereby compressing spring 18 and permitting the plunger 2O to rise so that it will be above the top of the newly cast type, when the type is raised to the level of the top oi the mold by the body plate 101, as clearly shown by Fig. 2 of the drawings, and the plunger rod 52 with its anti-friction roller 53 have continued to rise, after stopping at a point to hold the bottom of the pusher plate 55 even with the top of the mold until the plunger 20 has moved out from under the anti-friction roller 53, durj ing the movement of the mold-cover 2 to the lett, until the parts are in the position shown by Fig. 2 of the drawings, when the direction of movement of the 1noldcover 2 is reversed and the cycle of operations is repeated.

It will be observed that the mold-cover 2 vis only clamped tightly against the moldbeam 1 by the clamp 41 when in a condition of rest and that the pusher plate 55 only rises outor1 the loose channel 57 far enough to clear the top of the mold so that if a type sticks to it, which will sometimes happen, the type will be scraped off into the loose channel 57 by the movement of the moldcofver 2 and slidable jaw bar 36 toward the le t.

lWhat is claimed is:

1. rlhe combination in a type-casting ma chine of members forming a tight channel to receive type, one of said members being cut away adjacent the receiving end of said tight channel to a depth suiicient to take in several type whereby a loose channel is provided to first receive the type, movable jaw members adapted to transfer a molded type to said loose channel, and a plunger for pushing the type into and through said channels.

2. The combination in a type-casting machine oi movable jaw members adapted to transfer a molded type to a point over the channel of the machine, a plunger, means for moving said plunger to force type through the said channel, a nick guide, a

member coacting with the nick guide tov Jform the said channel, the said member being beveled at its type receiving end to a depth suflicient to talre in several type so as to provide a loose channel in which the type are irst received, and a tight channel into and through which the vtype are pushed by the plunger.

3. rlhe combination in a type casting machine of a reciprocative mold-cover, a plunger carried thereby, means for positively moving said plunger in one direction, mold, a clamp for clamping said mold-cover against said mold, and a member carried by said clamp for positively moving said pluni ger in the opposite direction.

i. The combination in a type-casting mae chine of a mold, a moldrover reciprocative thereon, an immovable standard, a rocker arm provided with a boss caried by said standard, a clamp provided with a cylindrical stem passed through an aperture in the boss on said roclrer arm, screws carried by said clamp and located on opposite sides ot the axis of said stein to cant or turn the clamp, the said clamp being provided with two arms adapted to press the moldecover against the mold.

5. rl`he combination in a type-casting machine of a mold, a mold-cover reciprocative thereon, a cage secured to said mold-cover and reciprocative therewith and adapted to inclose the jet on the end of a type, a. lined jet breaker adapted to break the jet from the end of the type, and a jet chute located adjacent to said j et breaker and over which the said cage is adapted to be carried during the reciprocation of the mold-cover to permit the et broken from the type to fall into said et chute. l

6. The combination in a type-casting machine of a mold-beam provided on its end with a nick guide, a reciprocative moldcover, a slidable jaw bar, an upright member forming a channel with the niclr guide, the top of said upright member being beveled to form a loose channel into which type are adapted to be received, a pusher adapted to push type which may be in the said loose channel toward the said niclr guide, means for moving said pusher toward said nick guide, means for limiting the movement of said pusher toward said niclr guide, and means for moving said pusher away from said niclr guide, the last said means being actuated in unison with the movement of the slidable jaw bar.

7. rlhe combination in a type-casting machine provided kwith a mold and a channel into which type are transferred from the mold., of movable jaw members for trans-v ferring a type from the mold to a point over the said channel, a pusher plate for pushing a type into said channel, means for moving said pusher plate in one direction to push the type into said channel, and means for moving said pusher plate in the opposite direction and retaining the bott-om thereof substantially even with the top of the mold.

8. The combination in a type-casting machine provided with a mold andk a channel into which type are transferred from the mold, of movable jaw members adapted to transfer a molded type to a point overthe channel of thek machine, a pusher plate, means for moving saidpusher plate in one direction to force a type into the said channel, means for moving said pusher plate in theopposite direction, and means to limit the movement of the pusher plate, when it is being moved in the said opposite direction so that, during a part of the movement of the movable aw members from said channel toward said mold, the bottom of said pusher plate will be maintained substantially even with the top of the mold.

9. ln a type casting machine having a type dressing channel, the combination with a mold, reciprocative means for transferring type from the mold to said channel, and a reciprocative pusher plate movable transversely to the movement of said transferring means for forcing the type from the transferring means into said channel, of means for arresting the withdrawal of said plate with its working face close to the opening into said channel as the transferring means is withdrawn toward the mold.

10. ln a type casting machine provided with a type dressing channel having a widened receiving end, the combination with a mold, reciprocative means for transferring type from the mold to said channel compris" ing a slidable jaw bar movable across the opening into said channel and closing the same when said reciprocating means is withdrawn toward the mold, and a reciprocative pusher plate movable transversely to the movement of said reciprocative means into and out of said channel, of means adapted to temporarily arrest the 'withdrawal of said plate with its working face close to the opening into said channel until said opening is closed by the slidable jaw bar in its return movement.

11. ln a type casting machine the combination with a mold and reciprocative means for transferring type from the mold, and a nick guide arranged transversely to the travel of said transferring means and forming one wall of a type dressing channel, of a member forming the opposite wall of said channel, said member being cut away to produce an enlargement of said channel at its receiving end and to allow for overthrow of said transferring means and being recessed adjacent to the enlargement of the channel, a pusher inserted in the recess of said member, and means for moving said pusher' toward and from the nick guide.

12. ln a type casting machine. provided with a type dressing Channel, the Combination with a mold and means for transferring type from the mold to said channel, a re- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of atents,

tively withdrawing the pusher from and Clear of said channel before the transferring means begins its return movement.
